This inventionrelates' to improvements in crane trolleys, and moreespecially to such a trolley designed for the purpose of handling a hotmetal ladle and tilting the ladle with-.

out help from. a ground-man. While themechanism is especially adaptedfor this -pur-.

Y pose, it will be-obviousfrom this disclosure that it might be used forother purposes, such as turning of'forgings, manipulating tongs, etc. .7f

The primary. object of the' invention is to provide a crane trolleymechanism including a hook actuatedfrom the trolley, toengage the lowerportion of a ladle, and means cooperating with the hook for elevatingthe latter to tilt the ladle and thus pour-the contentsof the latter. Va 1 Another object is to furnish mechanism of this character, all partsof which'may be controlled by a single operator. i =1 lv thxthefforegoing objects outlined and with other objects inview whichwill-appear as the description proceeds, the invention consists in thenovel: features hereafter de-: scribed in deta1l,'1llustrated lIlthe-accompointed out in the appended claims.

Referring to the drawings, 10 designates the body or platform ofatrolley carriage having supporting wheels 11 which travel on the usualcrane tracks (not shown).

The main hoisting drum of the trolley is shown" at 12, and it isdrivenin the usual way by anelectric motor 13. -Cables 14 are woundon-the drum. Each of these cables has one of its ends-secured to thedrum, and

its other end anchored to the carriage as shown at 15. These cables haveportions depending from the carriage and passing about pulleys 16'whichare mounted on axles supported by a ladle elevating frame 17 whichis used to raise and lower ladles containing. moltenmetal." One of theseladles is shown" at 18. It will be obvious that when the mo tor 13isactuated, the drum 12 can be turned: to wind: or unwind cables 14, andthis will result in elevating or lowering the ladle.

In accordance with my invention, the ladle.

other end'anchored to the carriage, as shown at 23. Depending portionsof these cables pass about a pair of pulleys 24, and from the" axles of,theseipulleys, a link 25 depends.

This link partially supports, and is pivotally connected at 26 tovaladle tilting hook 27 which is adapted to engage either one of the bars28. Each one of these bars is rigidly connected toa pair of cars 29 thatare rigid with the lower end portionof the ladle.'--It will be clearfrom Fig.3 that when the hook is in engagement with one of the bars 28,and.

is elevated while the frame 17 remains stationary,'the ladle will betilted on its trunnions 19 for the purpose of pouring from the ladle;

As part of my inventio-mI have means for Two cables 22 are wound seemoving the lower extremity of the-hook 27 toward and away from theladlefor the purpose of connecting the. hook to one of the bars 28. Tothis end, a lever 30 is pivotally mounted on the axle 31, and is rigidlyconnected with the casing 32 of a pulley 88 which rotates on an axle 34.The pulley 33is susfrom one end of a lever 37. The other end of thislever is mounted on a fixed shaft 38 that projects from one end of thetrolley carriage. For the purpose of raising or lowering the free end 39of the lever 37, the medial portion of the latter is supported by a link40,and the upper end of the link ismounted V on a crank'pin or eccentric41, which extends from a shaft 42. The latter, as best shown in Fig. 6,is fixed to a worm gear 43, driven by a worm 44, which is operated by anelectric notor 45, and is arranged in a casing 46.

' Atthis point it will be noted that all of the motorsof the trolleywill be connected by a suitable wiring to a common control board, notshown, in order that a single operator may control the travel of thetrolley along its tracks, the raising and lowering of the ladle, .theswinging of: the hook 27, and the tilting of the ladle.

In order that the raising and lowering of the pulley33 will act to swingthe hook on thepivot 26, the axle 34 is secured to the,

upper ends of'links 47, and the lower ends of these links carrya crosspin 48 which ex i tends through a'slot 49 at the upper end-of the .willdrop downwardly, and the hook will, swing about the pivot 26, so as tobring the hook 27. The slot permits of a small amount of movement of thehook 27 without moving the block or pulley 33while tilting the ladle.

In operation, assuming that the frame 17 haselevated the ladle andcarried' thelatter 1. to the point of pouring, at such time, the hook27- willbe in the dotted line position shown in Fig. 4, at which timethe crankpin 41 will be above the shaft 42. Now, if the motor 45 isactuated, the shaft 42 can beturned to lower the crank pin 41 so thatthe pulley 33 lower extremity of the hook beneath the bar 28 at the leftside of the ladle. I v

Now, when the motor 21 is started, the

cables 22, and will be wound, so that the hook 27 will be elevated totilt the ladle about itstrunnions 19, or into the dotted line positionof the ladle, as shown in Fig. 3, Of course, when the parts are returnedto the position shown in Fig 4, and then the motor 45 is actuated, itwill cause the crank pin 41 a to again move to a point above the shaft42,

with the result that the'hook will be moved from the full line positionof Fig. 4, to the dot-ted line position of that figure.

From the foregoing it is believed thatthe construction, operation, andadvantages of the invention may be readily understood, and

I am aware that changes may be made in the details disclosed, withoutdeparting from the spirit of the invention, as expressed in the claims.V Q
